+1.25 sight means what . Is it long sight or short sight

Are you asking about reading glasses or your actual site without any glasses or contacts?

If you use the lens to see better at distance AND near, it is "farsightedness". If it makes your distance vision blurry and near vision better, it is "presbyopia" correction.

This means that you are being corrected for "close-up" vision 1.25 diopters.
